For Hosting Providers

Disk and Quota

Use this feature to set the mailbox quota, or manage disk usage.

Mailbox Quota

The quota for an email account defines the amount of mail that the account can store. When the account exceeds this limit, the system returns any incoming mail to the sender with a message that states that the recipient’s mailbox is full. The system administrator can change this behavior in WHM's Exim Configuration Managerinterface (WHM >>Home >> Service Configuration >> Exim Configuration Manager).

Notes:

Make certain that you track your quota usage. A mailbox with a full quota cannot receive mail.

The quota calculation does not include your mailbox's trash folder.

Due to mail server constraints, you cannot assign quotas greater than 4096 TB (4 PB). You must assign the Unlimited value for quotas that exceed this amount.

If the Maximum option appears instead of the Unlimited option, your hosting provider does not allow unlimited email quotas.

You cannot assign custom quotas that exceed the Maximum value.

The system calculates mailbox quota use every four hours. For this reason, you may not receive notifications immediately if an email account reaches or exceeds its quota.

You can select different file sizes, for example MB, GB, TB, and PB.

Only enter whole numbers.

To change a mail quota, perform the following steps:

Click Disk and Quota.

Select the Unlimited or Maximum. For a custom quota, enter a new amount in the Mailbox Quota text box and select a file size from the menu.

To access this feature, click Set Up Mail Client in the Email Accounts tab. A new interface will appear.

Notes:

An email client must already exist on your computer or mobile device for you to automatically configure it with cPanel.

You must manually configure email clients that the interface does not list. For more information on how to manually configure an email client, review that client's documentation on the client's website.

To configure your mail client, perform the following steps:

Select and download the appropriate configuration file from the list.

Note:

We strongly recommend that you use SSL/TLS.

Run the script file to automatically configure your email client to use the selected address.

When the configuration process finishes, your email client will automatically open and log in to your email account.

Mail Client Manual Settings

You may need to manually configure your mail client. Enter mail.domain.com for the name of the server, where domain.com represents your domain.

Warning:

Only use the mail subdomain for the name of the server.

Email Instructions

To send a mail account's client configuration instructions to a different email address, enter the address in the Email Instructions text box and then click Send.

Configure Calendars and Contacts

Use this feature to access your calendars and contacts on your personal devices. A new interface will appear.

Note:

This option only appears if your hosting provider enables the Calendars and Contacts feature for your account.

Default Email Account

Use this interface to access your default email address. The system creates this unique email account when your hosting provider creates your cPanel account. The account's username and password are identical to your cPanel account name and password.

Your hosting provider may configure this address to be a catch-all account. A catch-all account receives all of the mail sent to addresses on the domain that do not exist. This can cause the the default email address to receive a large amount of spam.

You can send, view, or delete mail on this account. To do this through webmail, click Access Webmail and select your desired webmail application. You can also click Manage Disk Usage to recover disk space. A new interface will appear.

The system uses account@domain.com as the default account, where account represents your cPanel account username and domain.com represents your main domain. You cannot rename, delete, or place a quota on the default account. We recommend that you create a separate email account for daily use.

The system also uses this address as the default From and Reply-to address on outgoing email that your account's PHP scripts send.

Note:

Because of the way the maildir mailbox format calculates disk usage, a discrepancy between reported and actual disk usage may exist for the default email account. For more information about mailbox formats, read our Mailbox Conversion documentation.

Configuration Options

Use this interface to enable or disable a shared address book. A shared address book allows you to include a system-managed address book that serves as a user directory and allows for collaboration.
